Even though I didn't plan that, I have now implemented the new profile equation back in Ath4. So here is the new release 4.4.0 - http://www.at-horns.eu/release/ath-4.4.0.zip
Attached is the complete sample project - just quickly sketched and simulated. The quality remains

There won't be any documentation for the moment but I think all has been written here in this thread some pages back. New parameters are available in the script files for the new formula (SE_*) -

Code:
  ThroatDiameter = 25.4                 ; [mm]
  ThroatAngle = 0                       ; [deg]
  Coverage_Horizontal = 95.0            ; [deg]
  Coverage_Vertical = 90.0              ; [deg]
  Depth = 100                           ; [mm]
  SE_s = 0.7
  SE_n = 4.0
  SE_q = 0.995  
  Depth.ConicSectionPart = 0.9          
  Shape = raw2rect  
  Shape.FixedPart = 0.2              
  Shape.CornerRadius = 35.0             ; [mm]
  SEExp = 2.5                           ; superellipse exponent

Marcel, think about coding (asymmetric) cinema waveguide in fixed position e.g. flush mounted in ceiling and cover defined 3D space. Mouth is parallel to ceiling and throat plane must be derived, here tilted 28 deg to ceiling and side wall.

The big wide horn - made with the latest ath4 would look like this. Wondering how that would sound
Simulation left for those with powerfull machines -

Code:
  ThroatDiameter = 35.0                 ; [mm]
  ThroatAngle = 0                       ; [deg]
  Coverage_Horizontal = 115.0            ; [deg]
  Coverage_Vertical = 50.0              ; [deg]
  Depth = 200                           ; [mm]
  SE_s = 0.7
  SE_n = 4.0
  SE_q = 0.995
  Depth.ConicSectionPart = 0.7
  Shape = raw2rect
  SEExp = 2.5                           ; superellipse exponent

Oh, it was only 53x21 cm. Then it would be more like this.
Just for fun.

ThroatDiameter = 35.0 ; [mm]
ThroatAngle = 0 ; [deg]
Coverage_Horizontal = 109.0 ; [deg]
Coverage_Vertical = 45.0 ; [deg]
Depth = 160 ; [mm]
SE_s = 0.7
SE_n = 6.0
SE_q = 0.995
Depth.ConicSectionPart = 0.5
Shape = raw2rect
SEExp = 2.3 ; superellipse exponent
